COMPOUND.

SPECIFICATION forming part of Letters Patent No. 665,403, dated. January 8, 1901.

Application filed May 3, 1900. Serial No. 15,345. (No specimens.)

To all whom it may concern:

Be it known that I, ERNST BUSHMAN, a citizen of the United States, and a resident of New York, (Stapleton,) county of Richmond,

and State of New York, have invented a certain new and useful Compound, of which the following is a specification.

My composition relates to a compound for covering walls, ceilings, 850.; and it consists of the following ingredients in the proportions stated, viz: oxid of zinc six parts; ulverized flip}; 6W puverized silex eig parts; solution of hora-x onea par caustic soda two partsasbestos four parts; water two parts, and s1 mate 0 potash and sod a enough to bring e composl ion 0 t e consistency of a thick paste.

The solution of borax above mentioned is made up of the following proportions: borax one part, andmtwo parts, heated to I Fahrenheit. The proportions specified refer to a eight.

This compound is applied while in its pasty condition as ordinary mortar and affords a 2 5 covering for interior walls, ceilings, or floors. Heretofore compounds of this nature have been made upon a lime basis, the lime being the principal constituent,and a resultant compound would be obtained that might be fire- 0 proof, but not altogether waterproof.

My compound is made up upon a strictly silicate basis, thereby assuring an absolutely waterproof compound when hardened, as wellas a fireproof and hard substance for covering interior walls, ceilings, &c., and the na- 35 ture of the ingredients composing my compound is such as to readily admit of the entire compound being tinted in any desired color.

The waterproof qualities, as well as the hardening qualities, of my compound enable it to be used as an wingfor walls and for sidewalks. It may also be used for various other purposes, as for the manufacture of bowls, baths, sinks, &c.

What I claim, and desire to secure by Letters Patent, is-

The above-described composition of matter consisting of oxid of zipp, pulverized flint, pulverized silex, Borax, caustic soda, silicate of potash and s oda, asbestos and water, in the proportions specified'fsubstantially as described and for the purpose specified.

In testimony that I claim the foregoing as my invention I have signed my name, in presonce of two witnesses, this 30th day of April, 1900.

ERNST BUSHMAN.
